CARD-lNDEXlNG DEVICE.

SPECIFICATION forming part of Letters Patent No. 793,332, dated June 27, 1905.

Application filed April 4, 1904. Serial No. 201.498.

To all [rim/1t 1'1 may concern:

Be it known that 1, Louis (J. WALK an, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of )lichigan, have invented new and useful Improvements in Card Indexing Devices, of which the following is a specification.

This invention relates to certain new and useful improvements in indexingcards; and the invention consists in applying to each card a metallic spring indexing-tab constructed substantially as described and used for indexing or identifying the cards in the trays or supports.

The objects of my invention are, first, to furnish a durable and quickly-appliial indexing-tab for indexing the cards; second, to fur nish a tab which will inclose or partially inclose a space on the card to which it is applied for the reception of a suitable indexing character, such as a letter or numeral; third, to furnish a tab which can be quickly and readily applied to the card and which can be removed at pleasure; fourth, to furnish a tab having a resiliency so as to clasp the edge of the card and leave on the front of the card a partiallyinclosed space, substantially as hereinafter described. These objects I accomplish by means of the mechanism illustrated in the acci'nnpanying drawings, in which Figure I shows a perspective view of a package of cards separated from each other, so as to show the face thereof, and provided with my improved index-tab. In a part of the figure l have removed three cards between 1 and :3," 5 and J," &c. Fig. 2 shows a block of cards as they would appear placed in a tray or drawer. Fig. 3 shows a modified form of the spring-tab detached from the card, said Fig. 3 showing an upward extension, which may be of any suitable form; and Fig. I shows my preferred form of helical-coil-spring tab. This tab is preferably made of metal and may be cut from a plate of thin metal, or wire may be formed in a helical coil and then flattened into proper shape.

In the drawings, A shows that portion of the coil which appears on the face of the card, and A shows that portion of the COll which i l l l l l l l in the figu res, and each tab being placed a little over to the right, so that when they are all applied to the cards they present the appearance shown in Fig. 2. I have shown in Figs. 1 and 2 two lines or two series of the tabs applied to the cards. It will be understood, however, that any number of series may be applied. In the space inclosed or partially inclosed by the curved portion A of the tab, as shown in Fig. l, I insert, by print or otherwise, a character to indicate or designate that particular card. .111 the example of my invention shown in the drawings I have indicated the cards by numerals from l to 31. The cards may be constructed in the ordinary manner, and the edge of the card inserted between the part A and the part A of the tab. The tab being in the form of a helical coil is tightened by turning it from right to left, always mahng it more securely attached. to the card. These tabs may be attached in the order shown,and the ind icating characters may be then inserted within the coil on the face of the card, as shown in Fig. 1, or the cards may be printed with these numbers and the tabs attached in place to inclose such characters after the cards are printed.

I do not wish to limit myself to the peculiar form of character used, as it will be evident that the letters or figures or possibly other characters might be used to indicate the cards.

I have found that a card of this construction possesses important advantages. In the first place it does not wear by use nor become injured in any way. In the second place it holds its position upon the card with great tenacity, it can be easily and quickly applied, it presents a pleasing appearance to the eye, and is, so far as l have been able to discover, an effective way of indicating the cards.

Having thus described my invention, What I claim to have invented, and desire to secure by Letters Patent of the United States, is-

1. A detachable tab for indicating-cards, involving a resilient strip of material spirally arranged, and its trend terminating and directed toward a center, adapted to be mounted upon the card, and having one end projectable over and upon the outer faces of the card, and surrounding a suitable indication thereon.

2. A detachable tab consisting of a helical strip wherein the coils are in the same plane, and having its trend terminating in a center,
